Abstract: To achieve high and uniform audio quality in mobile devices their microphones must be equalized. The equalization is typically done manually, requiring lab time, costly equipment, and experienced engineers. This paper presents an automated equalization procedure. It is done using a reference microphone and an external loudspeaker. Each internal microphone is tuned to match the reference microphone’s response to the excitations generated via the external loudspeaker. Additionally, each internal microphone’s equalization is amended with the inverse equalization characteristic of the reference microphone calculated against the chosen reference, e.g., specific certification requirements. This way the final equalization includes both the internal vs reference microphone delta and the correction required for the reference microphone to pass the chosen certification.
